I was thinking making Lenovo KBD to USB converter would be a good idea. The premade ones are insanely expensive and most of us have surplus keyboard(s) just laying around. What do you guys think?

Thinkpad4by3's Law of the Universe.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

What, like a connector for the T4x, one for the T6x-Tx20 , one for the X30x and definetly one for the 600X. Once you have the circuit, getting the case isnt too difficult.

T6x and Tx20 keyboard connectors are different.

X6x and X220 keyboard connectors are the same (I can vouch for this because I plugged an X61 keyboard on an X220 and most keys work); by extension, that includes the Tx10, Tx20, and Tx30.

Either design the board to allow different connectors to be soldered in, or give the microcontroller board an edge connector, which can be mated to adapter boards that have a specific keyboard connector.

The 570* and T4x are the same except with no power switch.

Good to hear. I've only seen a 570* once (didn't even get to use it), and the extent of my T4x experience is but a single dead T42 which i revived with an R52 board, and subsequently gifted to a friend.

I happen to have a BRAND NEW 570E keyboard. The keyboard got damaged around 2002, but about 2 weeks later, the LCD cable died. At that point, a A31 was already ordered and shipped by the time the new keyboard came in so it has just been sitting around.

It's a good starting point, but from what I've read (using Google Translate), the Trackpoint isn't connected to the microcontroller, but feeds directly to the Dell laptop board's internal PS/2 port.
el-sahef did mention that it was possible, since the tmk firmware has support for PS/2 mice (the Trackpoint module is PS/2) but requires a microcontroller board with more I/O pins and memory.

Right, he took a shortcut, but adding the trackpoint shouldn't be too hard if you already did the rest. He suggested the AT90USB1287 for this, but I think you can also use the AT90USB1286 which AFAIK just lacks USB OTG host capabilities and is widely available as teensy++ 2.0.

They are actually the same connector however the Fn key, and by extension all associated functions, don't work. I plugged a T/W500 kb into my first project T520 when I was short a keyboard and wanted to test the machine.
